SPECIFICATION forming part of Letters Patent No. 669,628, dated August 23, 1898.

Application filed March 31, 1898.

To 6055 whom it may concern:

Be it known that I, HENRY M. .QUACKEN-, BUSH, a citizen of the United States, residing at Herkimer, in the county of I'Ierkimer and State of New York, have in vented certain new and useful Improvements in Smoke-Consuming Apparatus, of which the following is a My present invention pertains to improvements in smoke-consumers for furnaces, the advantages and construction of which will be hereinafter set forth, reference being had to the annexed drawings, wherein'- Figurel is a front elevation of 'theappacertain portion of the apparatus, partly in line a: a: of Fig. 3;, Fig. '3, a top plan view of the plunger or piston-head 5 Fig. 4, a vertical 5, 'a horizontal sectional view of one of.the inlet-chambers; Fig. 6, a perspective view of the deflecting and controlling slides, and Figs. 7 and 8 views illustrating modifications.

The object of the invention is to provide suitable and simple means'for automatically into the furnace above the fire when the furnace-door is opened and also for'a period after the door is closed.

To this end the invention consists in pronace-door is opened are automatically and without further thought or action upon-the part of the attendant thrown into action,- permitting a determinate quantity of steam and airto be introduced above the fire so long as v the door remains open and for a certain period thereafter.

In the drawings Figsfl and 2 A denotes the fire doors, which open into the fire-chamber beneath the boiler C; Above the doors B thereare formed in the wall two openings below the level of the boiler. These openings are usually lined with an iron box or cas-' ing E. Within each of said openings there Serial No. 675,958. (No model.)

are mounted two slides F and G, Figs. 4;, 5, and 6, the side walls of the former slide being beveled or inclined at their forward ends,

forming inclined faces a. The upper slide G is provided with a forwardly-extending lip or deflector'H, which is inclined downwardly,

as indicated in Figs. 4 and 5, the angle of inthe lower edge of the slide rests, while upon the opposite side the casing is formed with a groove, into which extends the inturned or.

horizontal edge of the slide. It is manifest that either of these constructions maybe employed on both sides or that the upper part of the casing couldbeenlarged slightly to receive the slide, the edges thereof resting upon the protruding edges of the smaller lower portion. With any of these constructions the lower slide of course will be absent, and the deflector II will practically close the air-inlet when the'slide is drawn back. So,

too, the beveled faces a can be dispensed with and the deflector H made narrow enough to pass in between the upstanding edges of the lower slide. 7 v

J denotes a pipe leading from the boiler or other suitable Steanrsupply; the pipe passing across the front of the furnace in line with the openings D, suitable laterals K being connected thereto and extending into said openings'. A manifold L is connected to each of said laterals and a series of spraying nozzles or jets M extend out from said manifold.

A valve N is located in pipe J, its stem being connected to a lever O, which is pivoted to a link P, secured to a bracket Q, the bracket I extendingo'ut from the furnace-front.

B denotes a cylinder, which, as shown, is

6b -hooked 'Blld of a rod j, which-extends down ameter of the .cylinder is the samethroingh-v outwith the'exception-of a short'portion at {the lowerend, which is slightly. enlarged, as will be seen upon reference to F.ig.- 3. A hole low piston-rod S is mounted in a stuflingibox -.or,glan' d T, carried by the anpper enduof .the

upon its inner lower end a head or plunger U, provided witha series of vertical openings" or channels V, Figsi 2 and 3. v

- It will be noted upon reference 2 that the lower central portion of the plungervface is slightly out out or depressed, forming- .a downwardly-projecting rim-or skirt upon h p ra 'Acap or plate W, having a central opening X, is carried by the plunger and is so mounted thereon that it bears against the lower-edge of the depending skirt or'rimf, but is freeto move therefrom when the piston is elevated.

To maintainit inits place and to allow it to be'moved away from the plunger, twoscrews Y are mounted in pockets formed in the 'lunge'r, the end sorews'passinginto the cap or plate and .lightspringsZ being. mounted between the heads of the screws and the lower The upper end of the stem is threaded and engages with a thread formed internally upon the piston-rod, a suitable head or nut c' being inwardly-extending walls of the pockets.

carried by-the'stem at its upper end inor- ,der tofacilitate adjustment thereof. .A coilspring (1- is placed around the piston-rod, hearing at one end against the plunger and at the other against the packing-gland, the spring serving to normally hold theflplunger-a'nd'r'od depressed, g v

"A block e is secured to the upper end of the piston-rod and extends out sufliciently to project over a stud f, carried by the ilever O, or,if desired, a projection may be=formed 1 upon the blo'ck to engage the lever, this form being-a mere reversal of parts. ,So, too, lever 0 maybe dispensed with and the block,-

through asuitable arm 0, Fig. 8,.1nade to act directly upon stopsO -O, carriedby the valve-stem. A chain g connects jthefl-outer end of saidjever to'the block, the chain being of suchlength that the lever remains un-. affected until the piston-rod and plungeror head have nearly reached'the' upper limit of from .one end of: a lever 10, pivoted to a 1 bracket secured to the ceiling or o'thersuib' able support. A weight I is placed upon the ..leve r., between its fulcrum and said rod j.

the downward movement of --the'pl nn g'er1the valve-controllin g lever-1O remain s unaffected and the steam conseqnently'continues to flow through pipe J and-discharge intofthe firechamber. This condition exists until the pisan air-inlet formed therein; slide F mounted inlet.

ton-head reaches the enlarged portion of the cylinder, when the head e'comes into engagement with the lever-stud f, and as the oil can now pass freely around the side of the pistonhead the spring is no longerretarded and by a quick impulse or movement forces the piston rod and head to the lowest point, at the same time forcing the valve to its seat and shutting off the steam.

' 'From the foregoing it will be seen that when the doors are opened the steam is turned on and that for a period after they are closed the steam continues to flow. As above stated,the period of after-flow may be regulated by the adjustment of the stem 1).

Oil is the fluid preferably employed in the cylinder, though it is manifest that other fluids may be employed, if found desirable.

It will be noted in the construction of the cylinder and piston that the parts are readily accessible by simply removing the plug at the lower end, also that the valve or cap-piece W is of metal, insuring durability that is not present with the ordinary leather or rubber flap-valve.

Having thus described my invention, what I claim isr 1.
